Black Cow Collection Center provides lotto service.
It provides the same functions as the web service and was optimized for mobile apps.
All functions provided by this service are free, and there are no commercial services.

You can combine and create lotto numbers just for fun and using your own techniques.
You can analyze numbers, provide recommended numbers for those who are troublesome, create numbers with desired conditions, and save the numbers you create.
In addition, we have promoted user convenience with a simple and intuitive UI rather than a complicated UI.
